中南光学仪器厂根据我国有色金属熔炼需要,依靠本厂光学、精加工技术的优势,研制成功真空电弧炉观察镜。该项成果是利用光学系统,将电弧炉内熔炼金属的全过程,通过转像系统的转换,最后由投影物镜成像于定距离的投影屏上供观察。该观察镜与真空电弧炉、凝壳炉配套使用。成像清晰度:在熔炼全过程中,距离投影屏0.5米左右,观察者从投影屏上能清晰地观
Zhongnan Optical Instrument Factory according to China’s non-ferrous metal smelting needs, relying on factory optical, finishing technology advantages, the successful development of vacuum arc furnace observation mirror. The result is the use of optical systems, the entire process of melting the metal in the electric arc furnace, through the transfer system conversion, and finally by the projection lens imaging on a projection screen for a fixed distance for observation. The observation mirror and vacuum arc furnace, coagulation furnace supporting the use of. Image clarity: In the whole process of melting, from the projection screen about 0.5 meters, the observer can clearly view the projection screen
